1998 Assessment of undiscovered deposits of gold, silver, copper, lead, and zinc in the United States
Estimates of the tonnages and amounts of contained metal in undiscovered deposits, mineral deposit types.
Descriptive models, grade-tonnage relations, and databases for the assessment of sediment-hosted copper deposits--with emphasis on deposits in the Central Africa Copperbelt, Democratic Republic of the Congo and Zambia
This report describes compilation and evaluation results of data from the USGS global mineral assessment including new descriptive mineral-deposit and grade and tonnage models and spatial databases for deposits and occurrences, ore bodies and open pits.
Economic filters for evaluating porphyry copper deposit resource assessments using grade-tonnage deposit models, with examples from the U.S. Geological Survey global mineral resource assessment
This paper reports on a methodology that is used with estimates of undiscovered copper resources to evaluate the likely contribution that the predicted resources will make to mineral supplies in the foreseeable future.
Global mineral resource assessment--porphyry copper assessment of Mexico
Includes known resources and permissive tracts with estimates of the number of undiscovered resources likely to be present in the permissive tracts.
Porphyry copper assessment of British Columbia and Yukon Territory, Canada
GIS files representing the mineral resource assessment permissive tracts, deposits and significant prospects.
Porphyry copper assessment of Central America and the Caribbean Basin
Study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.
Porphyry copper assessment of eastern Australia
